There are definitely differences. Men in the Canadian Armed Forces often have a larger network. They have more colleagues, and they engage in activities with them on a regular basis. They'll go out for a beer or play golf, for example. Their social network is very well developed.
However, women, who make up barely 15% of Canadian Armed Forces, don't encounter many women during their career, so they have fewer opportunities to form friendships with other women.
Some of them work in occupations where there are no women at all. In addition, they move every two or three years, much like men. Women need deeper friendships. Over time, they move away from that side of their career that involves forming friendships with women. That's why the transition is more difficult for them when they leave the Canadian Armed Forces. They don't have a network of women to support them.
